History

• Since World War I, civilian U.S. automakers manufactured trucks for military purposes with an emphasis on 4-wheel drive and high-torque capabilities for superior hauling power.
  
  

Jeep Trailblazer

• Although not technically a truck, the military Jeep popularized the use of military heavy-duty vehicles for civilian use when surplus Jeeps were sold for civilian off-road work.
  
  

Power Wagon

• The Dodge Power Wagon was a versatile military vehicle due to its moderate full-size pickup truck configuration. It was an early forerunner to today's 4-wheel-drive pickup truck, according to Allpar.com.
  
  

Hummer

• The Humvee was developed in the 1970s to replace the Jeep and saw limited use as a civilian vehicle. The civilian version, named Hummer, manufactured to meet public highway standards, debuted in 1992.
  
  

5-Ton Models

• The 5-ton, 6-wheel-drive M-813 series military truck has seen extensive civilian heavy-duty work as soft-top or hardtop models with winch.
  
  

Vintage Still Running

• The M-35 model of trucks started production during the Korean War and changed little through the end of the Vietnam War in 1973, but it's still used today for 2.5-ton civilian farm and cargo trucks.
